Step-by-step

Run this scenario in DocketMath using the Statute Of Limitations calculator.

This guide walks you through running the statute of limitations calculator in DocketMath for New Hampshire (jurisdiction code US-NH). You’ll use the tool to compute the latest filing date based on your chosen start date and the calculator’s general limitations period.

Note: This is general information to help you use the tool. It’s not legal advice, and it can’t replace a fact-specific analysis of when a claim accrues and whether any exceptions apply.

1) Confirm you’re using the correct New Hampshire rule

For this walkthrough, DocketMath will apply New Hampshire’s general/default civil SOL period:

General SOL Period: 3 years
General Statute: RSA 508:4 (civil actions)
No claim-type-specific sub-rule found: This post uses the general/default period as the baseline. If a specific claim type has a different rule, that’s not covered by the “default” steps below.

2) Open the Statute of Limitations calculator in DocketMath

Start at the tool here: /tools/statute-of-limitations.

If you’re navigating from the blog or app UI, open the DocketMath section for statute of limitations and select the Statute of Limitations calculator, which corresponds to /tools/statute-of-limitations.

3) Select the jurisdiction

In the calculator:

Set Jurisdiction to **New Hampshire (US-NH)

This ensures the calculator uses New Hampshire’s default timeline settings consistent with RSA 508:4.

4) Enter the “start date” (the event date)

The key input is the date that triggers the limitations clock. In practice, people often use one of the following depending on the case context:

Date of the alleged wrongful act
Date the injury occurred
Date the harm first happened (or was first discoverable, depending on the specific theory)

For the calculator run, enter the date you intend to measure from. DocketMath will treat your chosen date as the anchor for adding the SOL period.

Tip: Because “start date” can depend on how a claim accrues, try to be consistent with the factual theory you’re modeling. If later you realize a different trigger applies, re-run with the corrected start date.

5) Choose/confirm the SOL period used (default: 3 years)

Because this guide is built on New Hampshire’s general rule, confirm the calculator is using:

SOL period: 3 years
Authority: RSA 508:4

If the interface offers rule options (for example, default vs. other settings), select the default/general option.

6) Run the calculation

Click the calculator button (often Calculate or Compute).

DocketMath will compute a result such as:

Expiration / latest filing date = start date + 3 years

Depending on the UI, you may also see additional date math details (for example, how many days remain if you enter “today” or a comparison date).

7) Interpret the output for decision-making

Use the output to compare:

Latest filing date (from DocketMath)
vs.
Your target filing date (the date you plan to file)

A simple modeling approach (not legal advice):

If your target filing date is on or before the latest filing date, it falls within the modeled 3-year window.
If your target filing date is after the latest filing date, it falls outside the modeled window.

8) Repeat with alternate start dates when facts are unclear

If you’re unsure which date should start the clock, re-run DocketMath using different candidate start dates. For example:

Model using the date you believe the injury began
Then model using a later date you believe more accurately reflects when the claim accrued

How outputs typically change: the latest filing date will shift based on the start date you enter, while the SOL period remains 3 years under the general/default rule.

Start date you enter	SOL period used	Latest filing date changes?
Earlier date	3 years	Yes—moves earlier
Later date	3 years	Yes—moves later

9) Record your assumptions

Before relying on the output, write down what you entered so you can reproduce or adjust it later:

Jurisdiction: **New Hampshire (US-NH)
Start date: **(your chosen anchor date)
SOL rule: **general/default (3 years under RSA 508:4)
Date of calculation / “today” value (if the UI uses one)

This is especially helpful if you later determine the true trigger date is different.

Common pitfalls

New Hampshire timing issues often come down to date selection and making sure the rule you’re modeling matches your situation. Common pitfalls include:

Using the wrong “start date.”
The expiration date depends heavily on your input. If the real trigger differs from the start date you used, the computed expiration date will shift.
Assuming the general rule always applies.
This workflow uses RSA 508:4’s general/default 3-year period. No claim-type-specific sub-rule was identified here, so specialized timelines (if applicable) won’t be reflected.
Comparing the wrong date.
Some people compare the SOL expiration date to when they first contacted someone rather than the actual filing date.
Mismatch in date math conventions.
If DocketMath uses a specific day-count or rounding convention, make sure your “target filing date” is in the same format the tool expects.
Treating multiple scenarios as equally valid.
If you model several possible start dates, only one start date (based on the facts and claim accrual rules) should ultimately control. Document which assumption you’re using.
Not accounting for tolling or exceptions (not modeled).
The steps above perform date math for the selected SOL period. Many legal timelines can be extended or paused by doctrines that aren’t automatically included in a basic SOL date calculator.

Try it

To test the workflow end-to-end, run one sample scenario in DocketMath:

Open the calculator: /tools/statute-of-limitations
Set Jurisdiction to **New Hampshire (US-NH)
Enter a start date (for example, the date you believe the wrongful conduct occurred)
Ensure the rule applied is the default/general 3-year period under RSA 508:4
Click Calculate
Note the latest filing date result
Compare it to your planned filing date (if you have one)

Quick checklist so the run is consistent:

When you finish, you should be able to answer: “What is the latest date DocketMath computes for a filing measured from my chosen start date under the general/default 3-year SOL rule in New Hampshire?”
